4. AIR SUPPLY
4.1. Recommended hook-up procedure is shown in fig.1.
4.2.  Ensurespraygunairvalve(ortrigger)isintheo󰀨positionbeforeconnectingtotheairsupply.
4.3.  Youwillrequireanairpressureof50psi,andanairflowaccordingtospecification.
WARNING! Ensuretheairsupplyiscleananddoesnotexceed43psiwhileoperatingthespraygun.Toohighanairpressureand/or
 uncleanairwillshortentheproductlifeduetoexcessivewear,andmaybedangerouscausingdamageand/orpersonalinjury.
4.4. Drain the air tank daily. Water in the air line will ruin the paint finish and damage the spray gun.
4.5. Clean air inlet filter weekly.
4.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be
 1/4”I.D.andfittingsmusthavethesameinsidedimensions.
4.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.

4.8. COUPLINGS
4.8.1. Vibrationmaycausefailureifaquickchangecouplingisconnecteddirectlytothespraygun.Toovercomethis,connectaleaderhose
to the spray gun. A quick change coupling may then be used to connect the leader hose to the air line recoil hose. Seeg’s1&2.
5. OPERATION
5.1. For best results, the gun should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke before
squeezing the trigger and release the trigger before finishing the stroke. This will enable you to accurately control the gun and material (fig.3).
5.2.  Sprayfromadistanceofabout6to10inchesdependingonthematerialandtheatomizingpressure.Thematerialdepositedshould
always be even and wet. Each stroke must overlap the preceding stroke to obtain a uniform finish. To reduce over-spray and obtain
maximum efficiency, spray with the lowest possible atomizing air pressure.
5.3. Controlling the fan spray and the fluid.
 a)Usetheneedle(paint)adjustmentknob(fig.5.2)toincreaseordecreasetheamountofpaintflow.
b) The atomizing air flow is controlled by knob (1). The volume of air input is controlled by knob (3).
c) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.
d) Turn the air nozzle (4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (5).
The spray pattern of the gun is variable from round to flat with all patterns in between. In normal operation, the wings on the
nozzle are horizontal as fig 5. This provides a vertical fan-shaped pattern which gives maximum uniform and even coverage when
moving the gun back and forth, parallel to the work surface fig.6.

6. CLEANING
FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE GUN IS CORRECTLY CLEANED AFTER EACH USE.
WARNING! Disconnect from the air supply before attempting any cleaning or maintenance.
6.1.  Immersethefrontendofthegunonlyinsolvent.Thesolventshouldjustcoverthefluidconnection.
6.2. Use a bristle brush and solvent to wash off accumulated paint.
8DO NOT immerse the entire gun in solvent as this will cause lubricants on the rubber seals to dissolve. Dirty solvent may also clog
narrow passages in the gun.
6.3. Flush the gun through with clean solvent.
6.4. Wipe the outside of the gun with a dampened solvent rag.
6.5. AIR NOZZLE, FLUID NOZZLE AND NEEDLE ASSEMBLY
6.5.1. To clean the nozzles, soak them in solvent to dissolve any dried material then blow them clean with air. Handle all nozzles carefully
and DO NOT make any alterations in the gun.
6.5.2. If you need to probe the holes in the nozzles, be sure to use a tool that is softer than brass; DO NOT use metal instruments.
6.5.3. Adjustthefluidneedlevalvesothatwhenthegunistriggered,airflowoccursbeforefluidflow.
7. MAINTENANCE
7.1. Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check that
you have the correct part, or unscrew, realign and try again. DO NOT use excessive force when re-assembling.
7.2. Lubricate the gun daily with a light machine oil.
7.3. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in.
8. TROUBLESHOOTING
A faulty spray is usually cause by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. Soak these parts in
a solvent that will soften the dried material and remove with a brush or a cloth. Never use metal instruments to clean the air or fluid
nozzles. These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle is
damaged, the part must be replaced before a perfect spay can be obtained.
View of problem Possible reason for problem Solution
Dried material in a dirty side port restricts
passageofair.Greaterflowofairfromthe
cleaner side port forces a fan pattern in the
direction of the clogged side.
Dissolve material into the side ports with
solvent, then blow the gun clean. DO NOT
poke the opening with metal instruments.
Dried material around the outside of the fluid
nozzle tip restricts the passage of atomizing
air at one point through the centre opening
of the air nozzle and results in the pattern
shown. This pattern can also be caused by a
loose air nozzle.
Remove the air nozzle and wipe off fluid tip
using a rag dampened with solvent. Tighten
the air nozzle
Material too thin or atomisation air pressure
too high.
Regulate material viscosity or reduce air
pressure.
Dirtbetweentheuidnozzleseatandbody
orlooselyinstalleduidnozzlewillcause
the gun to spit.
Removetheuidnozzle,cleanthebackof
the nozzle and the nozzle seat in the gun
body using a rag dampened with thinner.
Replace the nozzle and secure it tightly
against the body.
Materialbubblesor‘boils’inpaintcup. Atomised air flowing through the paint
channel to pot.
The paint nozzle is not tight enough. Air
nozzle is not completely screwed in. The
air net clogged and the seat is defective or
nozzle insert is damaged.
Tighten, clean or replace parts accordingly.
